About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX175-10
The AirTAC SAIJ50X175-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 165-175 mm usable travel window, allowing you to trim the nominal 175 mm stroke by up to 10 mm during commissioning without adding external stops. Built with an extruded aluminum barrel, it delivers 982 N of push force at 0.5 MPa and utilizes a SUS420J2 stainless steel piston rod for enhanced durability against moisture.
This model features PT tapered port threads (G1/4) and variable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without continuous live air pressure. For applications requiring position holding without air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX175-10 Is Used
Machine Setup Fine-Tuning
Dial in the exact retract position within the 165-175 mm window during initial commissioning to perfect a pressing or clamping operation.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when switching between slightly different product sizes without swapping cylinders.
Assembly Station Actuation
Provides 982 N of thrust at 0.5 MPa for extending and retracting tooling, using the rear stop to prevent over-travel on delicate components.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX175-10 the Right Cylinder?
Choose this 50 mm bore when an application requires approximately 982 N of push force at 0.5 MPa, stepping up from the 40 mm bore which provides 628 N. The adjustable stroke is particularly useful for product changeovers or fine-tuning machine setup, whereas a fixed-stroke SAI cylinder is adequate for static end-of-stroke tasks. Since the stroke is 175 mm, side loads are moderate, but external guides are still recommended for any unsupported loads to prevent rod binding.
When replacing an ISO 15552 cylinder, match the 50 mm bore, 175 mm stroke, 10 mm adjustment range, PT G1/4 port, and the desired mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets. Note that this SKU lacks a magnet; adding the -S suffix enables CMSE reed and DMSE electronic sensor compatibility.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ50 Adjustable Cylinder SAIJ50AX175-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 165-175 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not act as a lock to hold the load without air pressure.
